My 136 year old cactus started blooming in late October, and normally makes it until March or April.
She gets passed down from one family member to another with the room for her, and the desire to care for her. She survived trips from Oregon to Nebraska, Nebraska to Alaska, and then Alaska to Oregon.
Caring for her is easy… She likes about 1qt/1l of water every two weeks, and a small rotation every month. The key is the water, we call it "fish poop water". We agitate the water in the fish tank to get everything moving, and use that particulate filled water.
She lives on an old console sewing machine in a large pot with south and southeast facing windows.
